IMPROVING RESISTANCE AGAINST OPEN FIRE AND FIRING

摘要

Improving the resistance of polymeric organic materials to adverse actions of high temperatures, especially to fire, e.g. open fire, flames, e.g. flame spread, through methods and/or compositions in which, before solidification, the polymeric organic material is mixed with waste residues originating from desulphurisation of flue gasses and/or with mixtures of calcium hydroxide and calcium sulphite hemi hydrate, possibly added smaller amounts of other comminute inorganic materials comprising crystal water.
